If neither level-1 nor level-2 is specified in this command, this command takes 
effect on both levels by default.

Use the timer lsp-generation command to set the time interval to generate LSPs 
(link state packets).

Use the undo timer lsp-generation command to restore the default setting.

When an event occurs, a new LSP needs to be generated for the IS-IS protocol. But 
the frequent generation of LSPs will result in the occupancy of huge resources and 
thus decrease the performance of the routing switch. To avoid the great decrease 
of the performance, an exponent decrement method is adopted for the 
generation of LSPs. You can set the intervals to generate LSPs as required.

# Set the intervals to generate LSPs to 10 500 2500.

isis timer retransmit seconds

Interface view

seconds: Specifies the retransmission interval of LSP packets, in the unit of second, 
in the range from 1 to 300 and the default value is five seconds.

Use the isis timer retransmit command to configure the LSP retransmission 
interval over the point-to-point link.

Use the undo isis timer retransmit command to restore the default setting.

Use caution when setting this parameter to avoid unnecessary retransmission.

The response is required when sending LSP packets on the point-to-point link, not 
the broadcast link, and therefore this command is unnecessary for the broadcast 
link.
